RE: difference between Bison Pitts and Slimline Q muffler
The Bissons I have are all real mufflers with baffels built in. My Slimlines are nothing more then A can with pipes. All my Slimlines are older, 5 to 8 years at least so they may have changed them?? I haven't bought A new one in over A year and it was A Bisson.
